From the previous illustration, notice the skids for easy sliding and the attached rope or chain, with and inferred (and out of view) anchor point on the box.
Notice both skids and an anchor point are absent/missing from the Smith's cove box.
I have attached the two photos of the box for the purpose of showing two different configurations. You should notice none of the sections appear to be attached in any permanent way to any other section. There were no iron nails or any other method to fasten the sections together.
Notice the following
In both photos section 3 is supported by a rock thus it cannot be attached to either 1,2,or 4
In photo 1, section A3 is on top of section A4, while in photo 2, B3 is beside section B4, see intersection IA34 and IB34.
In photo1 the length of A1 = A2, in photos B1 is much longer than B2. The reason is due to the missing section being removed for testing.
In photo 2 B1 shows a hole, A1 does not. Either the hole does not go all the way through, or A1 and B1 were swapped between photos.
It is difficult to tell the position of A6 and B6 in each photo and the relationship to other sections.
I personally think the section may have been found loose, rather than in a solidly formed structure; thus arranged after discovery ito give the appearance of a box.
